The Communication-Based Train Control (CBTC) system will be implemented by Kolkata Metro, the nation’s first metro system, allowing driverless train operations on two routes. At a cost of ₹800 crore, this modern signalling overhaul would automate train.
operations, doing away with the necessity for motormen. The routes Joka-Esplanade and Kavi Subhash-Biman Bandar will both use the CBTC technology. The East-West Metro corridor already makes use of this technology, according to officials.
Kolkata Metro to Implement Driverless Technology with CBTC System
In a groundbreaking development, Kolkata Metro is set to introduce driverless train technology by implementing the advanced Communication-Based Train Control (CBTC) system. This move aligns Kolkata Metro with global urban transit networks that rely on automation for safer, faster, and more efficient operations.
CBTC System: The Backbone of Driverless Metro Operations
The CBTC system is a cutting-edge signaling technology that allows real-time communication between trains and control centers, eliminating the need for conventional trackside signals. By implementing CBTC, Kolkata Metro aims to:
- Enable driverless and automated operations
- Improve train frequency and reduce delays
- Enhance passenger safety through precise train control
- Optimize energy consumption and operational efficiency
With this upgrade, Kolkata Metro will join the ranks of Delhi Metro and Mumbai Metro, which have already deployed CBTC-based systems for improved urban transit.
Deployment and Phases of Implementation
The introduction of CBTC technology will be executed in phases, beginning with the New Garia (Kavi Subhash) to Hemanta Mukhopadhyay stretch of the Orange Line (New Garia to Airport corridor). Over time, the technology will be extended to other metro corridors, including the existing North-South Line and the upcoming East-West Line.
The CBTC system will support automatic train operation (ATO), with initial human supervision before transitioning to full driverless mode. The system is expected to significantly reduce human errors, improve punctuality, and allow for higher train frequency, reducing waiting times for commuters.
Why CBTC is a Game-Changer for Kolkata Metro
Kolkata Metro, India’s oldest metro system, has long been in need of technological modernization. The adoption of CBTC will bring multiple benefits:
- Higher Efficiency: The system allows trains to operate at shorter intervals, increasing the number of services per hour.
- Reduced Delays: Automated operations minimize delays caused by human intervention or signal failures.
- Better Safety: CBTC ensures precise train positioning, reducing risks of collisions or manual driving errors.
- Sustainability: Optimized energy usage lowers electricity consumption, contributing to a greener metro system.
The Kolkata Metro Rail Corporation (KMRC) has partnered with leading global signaling technology providers to install the CBTC system. Extensive trials will be conducted to ensure safety and efficiency before full-scale implementation.
Challenges and Future Prospects
While the introduction of CBTC is a major step forward, challenges such as system integration with existing infrastructure, staff training, and public adaptation to driverless metro operations need to be addressed. The transition from manual to automated operations will require significant investment and operational adjustments.
The successful implementation of CBTC in Kolkata Metro will revolutionize urban transit in the city, making it faster, safer, and more reliable. With increasing urbanization and rising commuter demand, this technological upgrade is expected to transform Kolkata’s public transport landscape in the coming years.
